The TP-LINK TL-SM321B module supports the latest 1000Base-BX standard. Bi-directional data transmission is carried out on a single fiber using different wavelengths. The device guarantees high speed and excellent data transmission performance. Using TP-LINK devices, such as routers, switches or media converters, the transmission distance can increase up to 10 km.
